提出了利用1570 nm的连续激光和1565 nm的脉冲激光混合抽运铥/钬共掺光纤获得脉冲激光输出的方案，搭建相应的实验平台，得到了混合抽运方式下的2 μm稳定脉冲激光输出。同时进行了直接增益开关方式获得脉冲输出的实验。对两种方式获得的脉冲进行了对比。实验结果表明，在相同输出功率水平下，混合抽运方式获得的脉冲激光更加稳定，能量浮动小于5%。相对于直接增益开关方式，混合抽运方式在获得更加稳定的脉冲激光输出上具有一定优势。但直接增益开关方式获得的激光输出的脉宽要小于混合抽运方式获得的激光脉宽。

The concept of hybrid-pumped Tm-Ho co-doped pulse fiber laser by pumping the laser with a 1570 nm continuous-wave laser and a 1565 nm pulse laser is demostrated. The experimental setup is built up and stable pulse train of 2 μm is obtained. Directly gain-switched pulse train of Tm-Ho co-doped fiber laser is generated to compare the two methods of generating pulse laser. The results show that the hybrid-pumped pulse train is more stable than the gain-switched pulse train at the same laser output power level, and the energy fluctuation of the hybrid-pumped pulse train is less than 5%. Hence, the hybrid-pumped method is a more effective approach to generate stable pulse train. It should be noted that the pulse width of gain-switched pulse is narrower than that of the hybrid-pumped pulse.
